Detailed Description

Base class for dealing with files.

This class just provides things which are common among OFile and IFile

Constructor & Destructor Documentation

PLMD::FileBase::FileBase ( const FileBase &  )

private

Copy constructor is disabled (private and unimplemented)

PLMD::FileBase::FileBase ( )

protected

Private constructor.

In this manner one cannot instantiate a FileBase object

PLMD::FileBase::~FileBase ( )

virtual

Virtual destructor (allows inheritance)

Member Function Documentation

std::string PLMD::FileBase::appendSuffix ( const std::string &  path, const std::string &  suffix  )

staticprotected

Append suffix.

It appends the desired suffix to the string. Notice that it conserves a possible ".gz" suffix.

void PLMD::FileBase::close

(

)

Closes the file Should be used only for explicitely opened files.

bool PLMD::FileBase::FileExist

(

const std::string &

path

)

Check if the file exists.

FileBase & PLMD::FileBase::flush ( )

virtual

Flushes the file to disk.

Reimplemented in PLMD::OFile.

bool PLMD::FileBase::isOpen

(

)

Check if a file is open.

FileBase & PLMD::FileBase::link

(

FILE *

fp

)

Link to an already open filed.

FileBase & PLMD::FileBase::link

(

PlumedMain &

plumed

)

Link to a PlumedMain object Automatically links also the corresponding Communicator.

FileBase & PLMD::FileBase::link

(

Communicator &

comm

)

Link to a Communicator object.

FileBase & PLMD::FileBase::link

(

Action &

action

)

Link to an Action object.

Automatically links also the corresponding PlumedMain and Communicator.

virtual FileBase& PLMD::FileBase::open ( const std::string &  name )

pure virtual

Opens the file.

Implemented in PLMD::OFile, and PLMD::IFile.

PLMD::FileBase::operator bool

(

)

const

Check for error/eof.

FileBase& PLMD::FileBase::operator= ( const FileBase &  )

private

Assignment operator is disabled (private and unimplemented)

void PLMD::FileBase::setHeavyFlush ( )

inline

Set heavyFlush flag.

void PLMD::FileBase::test ( )

static

Runs a small testcase.
